Ketone functionalized polymers, methods of making ketone functionalized polymers, and compositions including the same
A ketone-containing polymer can provide for a paint having increased scrub resistance and decreased changes in viscosity, while maintaining quick dry times. In particular, the polymers may be used in compositions for traffic markings and industrial coatings.
